[Chorus]
And I know it makes you nervous
But I promise you, it's worth it
To show 'em everything you kept inside
Don't hide, don't hide
Too shy to say, but I hope you stay
Don't hide away
Come out and play

[Verse 2]
Look up, out of your window
See snow, won't let it in though
Leave home, feel the wind blow
'Cause it's colder here inside in silence
And you don't have to keep it quiet

[Chorus]
Yeah, I know it makes you nervous
But I promise you, it's worth it
To show 'em everything you kept inside
Don't hide, don't hide
Too shy to say but I hope you stay
Don't hide away
Come out and play

About “​​come out and play”

“come out and play” is Eilish’s fifth release since the release of her EP, don’t smile at me, leading up to her still untitled debut album, which has been teased to release in early 2019, as the singer shared in an interview with Annie Mac on the British radio station BBC 1.

The song was written for Apple’s 2018 holiday ad campaign, “Holiday – Share Your Gifts”, as shared by Eilish’s brother and producer Finneas in a Tweet:

Billie and I got sent an incredibly early version of this commercial when they were still putting it together and we wrote this song while watching it. Beyond honored to be a part of this wonderful piece

The advertisement features a young woman who is creative but is too afraid to share her creativity to the world. This is not the first time Eilish has partnered with Apple, as she was one of Apple’s Up Next artists in 2017.

To launch the ad, Eilish performed the original track in an Apple Store in Santa Monica, California, together with her brother Finneas.

The track, which was not anticipated by fans, unlike some of the singer’s latest releases, was first teased when Eilish’s team took to Twitter to announce she would be taking over Zane Lowe’s World Record feature on Apple Music’s Beats 1 radio station on Tuesday 20th November, 2018.
